  Q: How to replace the transmission pan on Buick LeSabre?

  A: The first task before Oil Pan replacement requires vehicle lifting and support for a proper position. A drain pan should be positioned directly under the transaxle Oil Pan to collect the oil. The process of unbolted the Oil Pan requires extreme caution since damage to its sealing surfaces can produce oil leakage. Only remove the bolts from the front and sides of the Oil Pan before loosening the rear bolts by four turns. Use a rubber mallet or light prying motion to drain the fluid from the Oil Pan while checking its fluid color. Draining the transaxle fluid requires the removal of all Oil Pan bolts while using bolt removers to detach the Oil Pan and its gasket. You can reuse Oil Pan gaskets as long as their sealing surfaces remain unharmed during installation process and you should introduce Oil Pan and gasket into its place all at once. Fasten the Oil Pan bolts making sure they achieve a tightening torque of 14 nm (10 ft-lbs). The technician should lower the vehicle before filling the transaxle with dexron fluid or equivalent until the cold fluid level reading indicates the correct amount to prevent overfilling. Conclusion of the operation involves checking for leaks in the Oil Pan gasket.
